L'TYFE-SI'TT'I'WNG APPARATUS.

SPECIFICATION forming part of Letters Patent No. 599,390, dated February 22, 1898.

Application filed June ll, 1897. Serial No. 640,341. (No model.)

To all whom t may concern:

Be it known that we, LOUIS KOSSUTH JOHN- soN and ABBo'r AUGUSTUS Low, citizens of the United States, residing Vin the city of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Type-Setting Apparatus, of which the following is a specification sufficient to enable others Skilled in the art to which the invention appertains to make and use the same.

Our improvements relate to apparatus for forwarding types from the lower end of a typecontaining channel into position for removal to the compositors stick by hand,and is adapt` ed to effect the presentation of a single type or a plurality of types arranged to form a word or other prescribed combination of characters.

In its general arrangement and operation our present construction embodies the essential features of prior applications for patents made by us, as Serial No. 616,938, filed December 2li, 1896, Serial No. 614,165, lled December 2, 1896, and Serial No. 632,400, filed April 16, 1897, our present improvements being designed mainly to render the apparatus more accurate and delicate in operation.'

A distinguishing feature of our present invention consists in the special construction and arrangement of the actuating-lever and gravity-latch, by which the type-forwarding mechanism is controlled, in such manner that the gravitylatch holds the type-bearing finger out of the Way of the advancing type during the forward movement of the type-forwarding blade. Ve accomplish this by arranging the fulcrum of the actuatingdever so that the forward end of the latter tends constantly to descend and in forming a shoulder upon the gravity-latch, which engages with the stationary cross-bar against which the gravity-latclrrests, thereby sustaining the type-iinger in position to receive the advancing types without impeding their progress. Incidentally in this connection our invention includes means for adjusting this shoulder or rest longitudinally upon the gravity-latch for the purpose of setting the parts accurately with relation to each other and to the types to be handled. In fact, variations in the number of types to be removed simultaneously may thus be compensated `for without disturbing the pusher-finger, which has heretofore been made adjustable for this purpose.

Another feature of our invention relating to the trigger or releasing-lever consists in the formation of the latter at its forward end with a socket-post in connection with the use Vof an adjustable screw-post, to which the nger-piece is swiveled, so that the finger-piece, resting between the vertical lateral typeguards on the holder, may be raised or low ered with relation to the path of the pusher without rotation by simply turning the screwpost in one direction or the other, as the case may be.

Another distinguishing feature of our invention consists in a rotatable bearing-surface for the upper side of the forwarded type, arranged in conjunction with a stationary heel-bearing and lateral supports for the type, substantially as hereinafter set forth, whereby the frictional resistance to the withdrawal of the types is reduced to the minimum.

Our invention also includes the special cona struction of a channel-holder for pressing the channel against the inner supporting-wall of the holder, so as to insure the proper alinement of the channel with relation to the typeforwarding blade, the path of which is at one side of the channel.

In the accompanying drawings, Figure 1 is a front elevation of a series of our improved type-forwarding devices arranged side by side and illustrating their use in conjunction with each other in the form of a compositors type-case. Fig. 2 is a sectional elevation showing the parts at rest. Fig. 3 is a similar view showing the parts immediately after the withdrawal of the types last forwarded. Fig. 4 is a similar view showing the parts when the type-forwarding blade is fully retracted. Fig. 5 is a similar view showing the parts during the forward movement of the typeblade. Figs. 6 and 7 are elevations of opposite sides of the channel-holder. Figs. 8 and 9 are front and rear elevations of the channel-holder; Fig. 10, a plan thereof. Fig. 11 is a detail view of the finger-piece. Fig. 12 is a horizontal section illustrating the relation of the pusher-blade to the lower end of the type channel and holder; Fig. 13, a hori- IOO slot c', made in the path of the pusher-blade p, which path extends between said horizontal shoulder c and the opposed wall of the channel C.

The type-channel C is supported by and upon the slide S. This slide S iits into a vertical groove 7L', formed in the side of the holder H, and is made adjustable vertically bysuitable means, as by the vertical set-screw s, engaging with a female screw-thread formed in the lower part of the holder, as shown in the drawings, which construction is preferable in that the sides of the holder are left free and unobstructed, while the adjustment of the slide can be readily effected when the j It is holder H is removed from the table A. to be understood that this adjustment of the slide S is for the purpose of regulating the position of the type-shoulder c upon the channel C with relation to the position of the pusherblade p, the path of which is prescribed.

The channel is held in a ver-tical position by the wall h3 of the holder upon one side and by the `lateral arm W on the other. In our last application hereinbefore referred to this lateral arm W was pivotally supported on the rear of the holder H and tended constantly to press against the side of the channel by reason of the action of a spring w, so as to compensate for dierences in thickness of the ychannels which might be used in the holder `and to insure the alinement of the channel with relation to the pusher-blade p. In our present application we accomplish the same result in a more simple manner by making t-he lateral arm W itself sufficiently elastic to yield to allow the insertion of the channel, while thereafter tending to retain of the upper end of the finger-piece f. The cheek -pieces support the types laterally,

while the roller h6 reduces the frictional resistance to the withdrawal of the types.

P is the reciprocating pusher-bar, to which the pusher-blade p is attached. The pusher- This table a is formed with lsockets blade p is connected to the eccentric E by the pitman F and eccentric-strap. The eccentric E is loose upon the power-shaft I, except when coupled thereto by the pawl e, which engages with the shoulder z' on said shaft when not held out of engagement therewith by the upper end of the gravity-latch J on the inner end of the actuating-lever L. The shaft I is in constant rotation, so that directly the pawl e is released it encounters and engages with the shoulder 2, and thereby carries the eccentric E around with the shaft until the pawl e is again released, which occurs at the end of a single rotation, provided the type has been forwarded between the upper heel-guard g and the type-finger f, in

which position the type holds the actuatinglever L in such relation to the stationary bar R that the gravity-latch J tilts backward with its upper end in the path of the outer end of the pawl.

The protruding and retracting of the upper end of the gravity-latch J is effected by reason of the contact of its inclined surface j with the stationary bar R or its equivalent, the lower end of said latch J being pivoted to the actuating-lever L in such position that such inclined surface is held by gravity in constant engagement with said stationary bar R. The upward thrust of the gravity-latch J is limited by the shoulder j thereon, which thus also limits the downward movement of the finger-piece f.

Inorder to attain the greatest delicacyand accuracy in all the parts, as well as to compensatefor variations in the size or number of types to be removed simultaneously, this shoulder j' upon the gravity-lever J is made adjustable longitudinally thereon by any suitable means. As shown in the drawings, the shoulder j' forms part of a plate jg, which is secured to the gravity-latch J by set-screws js, passing through longitudinal slots ji, by which the distance between the saidshoulder j' vand the pivot of the gravity-latch may be varied or adj usted with accuracy to meet the requirements of actual use.

The finger-piece f is mounted upon the front end of the actuating-lever L, which latter isV so pivoted that its forward end tends constantly to move downward, which movement is limited by the stationary bar R, as aforesaid. The front end of the actuatinglever is formed with a socket-post Z, the upper portion of which is formed with an internal screw-thread Z,which engages with the male screw-thread f ony the portion of the shank or screw-post f2 which supports the .fingerpiece f proper. The ingerpiece f is swiveled to the screw post or stem f2 or otherwise so connected therewith that the shank f3 is free to turn independent-of the nger-piece f, the iiat upper end of which rests between'the cheeks h5, which prevent it from turning laterally on its axis. Thus in the drawings the upper end of the stem f2 has a small annular groove f4 turned in it, while the lower end of IOO IIO

the nger-piece f iits over this grooved end of the shank and is coupled thereto by a small screw or pin f5, projecting into the groove f4, but in no wise interfering with the rotation of the stem f2.

l/Vhen it is desired to adjust the iinger-piece with relation to the thickness of type or to thel number to be withdrawn simultaneously, the

set-screw Z2 is loosened and the nger-piece f raised or lowered by turning the shank f2 in one direction or the other, as the case may be, when the set-screw Z2 is again adjusted tosccure the parts in their new position. By the use of the threaded shank f2, turning in the threaded socket-post Z, we are enabled to attain a very delicate and accurate adjustment of the finger-piece f with relation to the roller Zt and type-heel g.
